Research Support with statement on research activities
A Wide-band Reflectance – DPOAE (WR-DP) Screener
SBIR DC00654-02 Phase II, Patricia Jeng (PI) - 11/01/2005 – 08/31/2007
This is a multi-center SBIR grant to investigate the utility of a wideband reflectance and distortion product otoacoustic emission (DPOAE) screening device for middle ear and cochlear function. Under a subcontract planned to start in the Fall 2005, Dr. Feeney will conduct testing with adults at the University of Washington Medical Center and the Seattle Puget Sound Veteran's Administration Hospital, and with infants at the University of Washington Medical Center. Susan Norton, PhD will conduct testing with children at Children's Hospital in Seattle and Lisa Hunter, PhD, will conduct testing with adults and children at the University of Utah Pediatric Clinic.

Longitudinal follow-up of hearing in construction workers
R01 Noah Seixas (PI) - 09/01/2005 – 8/31/2010
A cohort of over 450 construction apprentices and unexposed graduate student controls was enrolled and assessed annually over the past five years. Results demonstrated small but significant reductions in distortion product otoacoustic emissions (DPOAEs) in relation to hearing protection-adjusted noise exposure, especially around 4 kHz. We propose to continue studying approximately 300 cohort members who have had at least two previous examinations for noise exposure and hearing damage by measuring air conduction hearing threshold levels (HTLs) and DPOAEs.  An additional five years of evaluation of the early progression of noise-induced hearing damage among construction workers exposed to high but variable noise levels, and prospective documentation of the relationship between DPOAEs and standard HTLs, will provide much greater quantification of the risk and development of Noise-Induced Permanent Threshold Shift.

Presbycusis: Biomedical Risk Factors
R01 DC01525 Gates (PI) - 07/01/2003 – 06/30/2006
Age-related changes in the central nervous system often impair hearing, in particular, speech understanding in noise and other difficult listening situations. This is characteristic of people with central presbycusis, i.e. poorer speech understanding than would be expected from age-related peripheral hearing loss alone. People with early stage probable Alzheimer dementia (pAD) exhibit signs similar to people with central presbycusis except that these signs occur earlier, more prevalently, and to a greater degree than controls. By comparing the results of behavioral central auditory tests in the pAD and non-pAD subjects, while controlling for peripheral hearing and neuropsychologic status, we may better understand the effects of aging and dementing disorders upon central auditory function.
